UNITED STATES PATEMEE JOHN JONES, OFELKHART, INDIANA.

RAILWAY-CROSSING.

SPECIFICATION forming part of Letters Patent No. 425,803, dated April15, 1890.

Application filed November '7, 1889. $erial N0.329,5 56. (N0 model.)

To all whom, it may concern:

Be it known that I, JOHN JONES, a citizen of the United States, residingin the city of Elkhart, in the county of Elkhart, in the State ofIndiana, have invented certain new and useful Improvements inRailway-Crossings, of which the following is a specification.

My invention relates to improvements in a railway-crossing in which tworails are con nected together and pivoted at the point of intersectionof two tracks, so as to be changed from one track to the other, to beused upon either as required, in combination with a device, by whichdistant signals are interlocked with the crossing; and the objects ofthis invention are to give a smooth track and perfect safety for thepassage of trains running at high speed upon one track across another,both tracks being upon the same plane. I attain these objects bymechanism illustrated in the accompanying drawings.

Figure 1 is a plan view of acrossing of two railways, showing myimprovements in position. Fig. 2 is a sectional plan of the center ofthe crossing, showing the mechanism for lifting and turning the crossingand interlocking the distant signals. Fig. 3 is an elevation of thelower part of the center post and the sleeve which rotates about it,showmg a lever with friction-rollers for lifting the crossing above thetop of the permanent rails and lowering it into position for trains tocross, the dotted lines showing the position of the lever when thecrossing is up. Fig. 4 is a plan of the lever with the friction-rollers.Fig. 5 is a vertical section showing the center post and the rotatingsleeve and the manner of fastening the rails to the rotating sleeve andone of the interlocking bolts and its guide-post. Fig. 6 is aperspective view of the joint formed by the permanent rails of the trackand the rails of the crossing when in position for, trains to cross.Fig. 7 is a stand with lever and crank for rotating the crossing. Fig. 8is a similar stand with lever and sheave and cable for operating distantsignals, two of which should be used, one for each track. Fig. 9 is aplan of the sheave with cable, showing the interlocking bolt connectedto the sheave by the rod d. Figs. 10 and 11 are side and end views of anordinary Windlass for lifting the crossing and lowering it into positionfor trains to cross by means of the cable 0.

Similar letters refer to similar parts in all the figures.

In the drawings, R R represent the permanent rails of one track, R R thepermanent rails of the other, whose ends are bent outward and connectedtogether by the straps V, as shown at a a and a a in Fig. l.-

R R represent the pivoted rails of the crossing, which are secured tothe central rotating sleeve A, and are held the proper distance apart bythe braces 13 I3 and B B, the rails R B being planed or cutoff at eachend at an angle to coincide with the bent ends of the rails R R and R R,as shown at a a in Figs. 1 and 6. TherailsR R when in position for atrain to cross, are down between the bent ends of the rails R R or R R,as may be required, and are supported laterally by the permanent rails,and resting their entire length upon the timber below form a smooth andcontinuous track without butt-joints across the intersecting track.

L in Fig. 3 represents the lever under the lower edge of the sleeve A,the forked end pivoted to the lugs G on the base-plate of the post P.

0 represents the rod for rotating the crossing from one position to theother.

E represents the bolt by which the rod 0 is connected to the sleeve A.

J is a lug on the sleeve A to support the lower end of the bolt E.

F and F represent the boltsby which the distant signals are interlockedwith the crossing,'so that neither signal can be changed from dangertill the crossing is in position for a train to cross. Then the signalsfor the track which is connected can be changed to show clear. Then thecrossing is locked so that it cannot be lifted and the signals for theother track are locked at danger. The manner of doing this is asfollows: When the crossing is lowered into the position shown in Fig. 1,the hole H in the sleeve A (shown in Fig. 2) is brought into line withthe hole N in the post P, about which the sleeve A r0- tates, and allowsthe bolt F to pass through the outer sleeve A and into the post P, asthe signals are set at clear by the movement of the sheave S, Fig. 9,mot-ion being transmitted to the bolt Fby the rod (1 through thebell-crank 'K, and the bolt F having been previously withdrawn andmotion being transmitted through the bell-crank K by the rod d, whichsets the signals for the track R R at danger to allow the crossing to bechanged from R R to R R, and are held there by the sleeve A covering thehole N in the post 1?, as shown in Fig. 2, thus preventing the crossingfrom being lifted or the danger-signals for the track R R being changedtill the danger-signals are set for the track R R.

T in Fig. 1 is the tower or house from which the crossing and signalsare operated.

Having thus described my invention, What I claim to be new, and desireto secure by Letters Patent, is

1. The combination, in a railway-crossing, of the permanent rails R Rand R R, having their ends bent outward and secured to each other by thestrap V, with the pivoted rails R" R, having their ends planed off at anangle to coincide with the bend in the permanent rails R R and R R, therails R" R fitting between and resting upon the same plane and beingsupported laterally by the permanent rails, forming a joint bywhich thewheels are carried smoothly from one rail to the other, substantially asspecified.

2. In a railway-crossing, the combination of thesleeve A with the railsR R the post P, the lever L, and rod 0, for lifting and turning therails R R", substantially as described, and for the purpose specified.

3. In a railway-crossing, the combination of the rails R R, the braces BB, the sleeve A, the hole H in the sleeve A, the holes N and N in thepost P, with the bolts Fand F, connected to the mechanism by whichdistant signals are operated for interlocking the cross- 40 ing andsignals, substantially as described.
